Thermal cyclic symmetry using perfect contact thermal coupling

When you have a model that is rotationally periodic, you can simplify its geometry to only model the conduction on a portion of the model. This reduces the number of elements and the solve time. On the simplified model, you specify a Perfect Contact type of the Thermal Coupling simulation object. You must also specify:

• The primary region and the revolved secondary region.

• The axis of revolution that is defined by a vector and a point.

Rotationally periodic portion	Meshed solid

While calculating the conduction, the thermal solver revolves the secondary region (2) around the axis of revolution (3) to be in contact with the primary region (1).
